The solo Fantasias were intended for a traverse flute in D, and so would be best played on a voice flute (recorder in D -- not common, not cheap). However, you can easily find them transposed for alto. His other music with a flauta part is most often for alto.

Rule of thumb: if the Baroque music you're looking at has one or more sharps then it's mostly likely traverse flute music in the original key, and plays easiest on a voice flute and can perhaps be played on a tenor or soprano if it doesn't go too high. Otherwise you'll have to look at the range to make sure, but alto is by far the most likely choice.

Wrong. The alto's lowest note is the F above the middle C. The tenors lowest note is middle C. Soprano's lowest is the C above middle C. The Bass is the highest to go below middle C. Its lowest note is the F below middle C.
